Wet/flooded, gel-cell, AGM, and lithium 12V 100Ah deep cycle batteries are a very popular group of deep cycle and dual-purpose batteries, offering relatively large capacities (100+ Ah), a large amount of stored energy (1200+ Wh), and large discharge currents at acceptable price and weight.
Due to the maintenance requirements, wet/flooded batteries are used rarely, with the SLA Gel and AGM batteries being most common. Also, lithium 12V 100Ah batteries are getting more and more present on the market, offering huge weight savings.
Trolling motors are commonly used as means of propulsion on kayaks of various sizes, especially on fishing kayaks, intended for longer fishing trips that last for hours and sometimes even for days.
The main issue any kayak owner has is the kayak's load capacity. While electric trolling motors are lightweight and feature excellent weight to thrust ratio, their batteries are anything but light - unless lithium kayak trolling batteries are used.
Fish finder batteries for kayaks and smaller boats must be lightweight and compact, but accept charge quickly from various sources, and should be able to power the fish finder during the entire fishing session without the need to be recharged before going to shore or starting the main engine (if present).
Fish finder batteries are spill-proof AGM and Gel-Cell lead-acid batteries and Lithium Iron Phosphate (LiFePO4) batteries. Most fish finder batteries feature nominal capacity in the 5 - 20 Ah range.
2000 Watt portable inverter generators are very popular units, offering reliable power from rather compact devices at an acceptable weight.
While 2000 Watt inverter generators differ in features and specifications, finding the best one often depends on personal needs, requirements, but also a budget.
Since automotive, marine, and industrial batteries are commonly used for powering both AC and DC loads, many people actually wonder if the simple car or marine battery is AC or DC power source?
This time, the answer is very simple.
Power inverters for cars and trucks are becoming increasingly popular due to the large number of devices and gadgets that must be powered or at least occasionally charged while in the car.
As such, car power inverters should feature a car cigarette lighter adapter plug (12V DC) providing high-speed charging for smartphones, tablets, cameras, drones, but also for laptops and similar devices. However, due to the power limitations of the car cigarette lighter adapter, the output power of car inverters is also limited.
Space heaters are commonly used for heating tents, RVs, offices, rooms, cars, and even homes and apartments. They directly convert chemical or electrical energy into heat, warming up the desired area. Since space heaters directly convert chemical energy into heat, they are simple, reliable, and rather affordable, but also they are not as efficient as, for example, Air Conditioning units.
Battery operated heaters can be of great help when camping or being off-the-grid by keeping You warm during long, cold days and nights. Right? Well, things are not that simple ...
Watts to BTU and BTU to Watts conversions are commonly required when calculating the power of devices that are used for air heating and cooling, like various AC units and electric heaters.
'Slight' issue is the fact that BTU is a unit of energy, while watts are a unit of power, and they can't directly be converted.
While HP is a unit of power, kWh is a unit of energy and direct conversion of these two units is not possible, without introducing the third parameter - time (T[s]).
kWh to HP and HP to kWh conversions are very important when both power and energy of internal combustion engines are transferred, stored, and compared with the energy and power of electric motors, inverters, pumps, winches, and other similar units that are powered by electric energy.
Power generators are used when electric power is needed and mains power is not present - when camping, tailgating, in emergencies, and similar.
One of the very important features of power generators is - noise level. A loud power generator can be very annoying, especially when working for a longer period of time. On the other hand, a quiet power generator is a robust and reliable, but almost silent unit, giving peace of mind in more ways than just one ...
Lead-acid and lithium 100 Amp-Hour batteries are commonly used in automotive, marine, industrial, and off-the-grid applications as starting, dual-purpose and very often, as deep-cycle batteries.
Since they commonly used in many critical systems (medical, security, etc.) many people wonder how long can a 100Ah battery last under a certain load.
Regardless of the car battery type or brand, from time to time it may become necessary to recharge the car battery using the battery charger. Was the battery discharged due to the parasite load, multimedia devices, or for some other reason, is not the topic of this article.
However, if that happens several times over a short period of time, check the alternator and the rest of the electric system of your car.

Refrigerators and freezers are used for preserving the food, cooling down beverages, and for other similar tasks. When the mains power is gone, refrigerators and freezers stop, with all the stored food and drinks being in jeopardy.
Regardless if You have a fridge that you want to keep operational during a power outage or you want to have a fridge or freezer running when camping, it is vital to know the power and energy requirements of your unit.
SI prefixes are very important in electrical engineering but also in everyday life. Their use is relatively easy, but it can also cause many problems when done incorrectly.
Watts to kilowatts, kilowatts to megawatts, and other conversions are very important when electric energy and power of electric motors, pumps, winches, inverters, batteries, and other devices are being calculated, planned, transferred, or being used. SI prefixes help significantly, especially when dealing with very large or very small values.
Unit conversions in electrical engineering are very important, it is relatively easy, but it can also cause many problems when planning or troubleshooting systems.
HP to kW conversion is very important when energy and power of internal combustion engines are compared or transferred between energy and power of electric motors, pumps, winches, inverters, and other devices being powered by electric energy.
Microwave ovens are very popular kitchen appliances commonly used for cooking and/or heating food and beverages. Microwave ovens are also very efficient devices, which is very important in many ways.
Due to their convenient nature, microwave ovens are commonly used when camping, on the boats, in the RVs and similar, leading many people to ask themselves, how many watts their microwave ovens actually use?
TVs are not used any more for just 'watching a TV' - they are used for 'watching TV', but also for media streaming, for gaming, as communication devices, part of security systems, etc. - it is vital to know how many watts and energy in general they require.
Regardless if You are worried about your electric bill or you want to watch TV during power outages, we bring You the TV wattage comparison chart taking into account TV sizes and technologies.
Choosing 'the best' car battery can be somewhat confusing, since just like cars, car batteries come in various sizes, shapes and also differ in terminal types and orientation, exact chemistry, CCA/MCA features, battery type, etc.
Picking the right battery means having the battery that will do its job for years to come, without leaving the user stranded with the dead car battery when needed the most.
Conversions between electrical units are usually simple and straightforward - take a formula, write down values, and let the calculator do the rest.
However, in real life, things are not always that simple, especially when converting units that require at least one unit to be known. If You wish to know more about converting watts to amps, amps to watts, volt-amps to watts, and similar, read carefully...
Many people wonder what is the required size of the power generator in order to run an air conditioner without any power issues.
2000-watt inverter generators are popular, compact, and affordable portable units that are used in many situations, leading to the question, will a 2000 watt generator run an air conditioner in the case of a power outage?
Lithium electric trolling motor batteries offer many advantages over lead-acid batteries, including lightweight design, a large number of charging/discharging cycles, a very low self-discharge rate, more constant output voltage, almost no capacity loss with the current increase, etc.
Also, lithium trolling batteries still have some issues, like high initial price and safety concerns. For safety reasons, lithium trolling motor batteries are almost exclusively Lithium Iron Phosphate (LiFePO4) batteries featuring built-in Battery Management Systems (BMS), protecting the battery from unwanted events like short circuit, overcharge, over-discharge, and similar.
Portable generators with 120/240V 50A (14-50R) plug and the list of other ports (L14-30R, L5-30R, 5-20R, 12VDC, etc.) are large, sturdy and powerful units, capable of providing plenty of energy over a longer period of time.
50 Amp portable generators are often used as RV generators, camping generators, in emergencies, on the construction sites and similar. They are usually powered by gas or gas/propane combination (dual-fuel models), with some larger industrial/commercial models featuring diesel engines.
2000 watt generators are a very popular class of power generators, featuring acceptable price, long runtime on a single gas tank, quiet operation, simple maintenance etc., and are thus often used for camping, boating, fishing trips, in RVs, etc. Also, they are often used in emergencies.
Thus, many people wonder what household appliances their 2000 watt power generators may run and for how long.
When powering home appliances using power generators and power stations, it is of utmost importance to know how much power our appliances require in order to operate properly and to avoid issues of overloading the power generators and power stations.
Our appliances chart includes the most common appliances, tools, gadgets used at homes, RVs, on the boats/yachts, during camping, etc.
Many people wonder if the car battery can die while driving, especially after their car battery died while driving. Obviously, answer is 'Yes, a car battery can die while driving'.
A cood car starting or dual purpose battery should not die while driving, but although it is rare event, it happens. There are many reasons why a car battery dies while driving, here are the few most common ones...
Most cars still use lead-acid batteries of some kind - wet/flooded, AGM or even Gel-cells, but these batteries over time lose their capacity and the ability to start the engine.
Since quality car batteries are not cheap, many people wonder how they can recondition a car battery at home. Reconditioning car batteries at home can be done successfully, but this also depends on the battery type, its use, age, current condition and similar.
Solar panel kits are great solution for powering hungry electric and electronic devices in various off-the-grid situations like camping, taking fishing trips, or simply when having issues with mains power.
Solar panel kits consists of one or more solar panels, power/charge controller and one or more deep cycle batteries for storing electric energy and are usually combination of solar panel/power (charge) controller/battery or solar panel/power station.
Battery powered sump pumps are type of emergency equipment that must operate reliably when required, and saving the money on these pumps or their batteries may be very expensive thing to do.
Sump pump backup battery must be strong enough to power sump pump motor and it must store enough energy to power the whole unit long enough to prevent as much damage as possible until mains power is restored.
Knowing your car's battery amps and other features is very important not only when replacing the battery, but also when the battery is being used not only for cranking purposes, but also for powering other electric and electronic systems like lights, navigation, multimedia devices, security systems, etc.
With more and more onboard systems, car manufacturers are slowly replacing pure starting batteries with the new dual purpose AGM batteries, featuring many improvements over older flooded ones.
Non-Rechargeable (disposable) zinc-air batteries have been standard hearing aid batteries for a long time. They have replaced older mercury-oxide batteries and after introducing mercury-free zinc-air batteries, they have become de facto standard for hearing aid batteries.
However, rechargeable batteries are being used more and more in everyday electronics and as such, they are slowly entering the hearing aid market as well. But, there are several very important issues that rechargeable batteries face when being used as hearing aid batteries...
Wrist watches are commonly powered using one or rarely two button/coin cell batteries, and these batteries have a limited operating lifetime. When replacing an old battery with the new one, the best practice is to use batteries recommended by the watch manufacturers.
However, finding the exact type and model can be sometimes confusing due to the different labels some battery brands are using for their batteries. Also, using silver-oxide instead of alkaline batteries can prolong the watch operating time on a single battery.
Marine batteries are designed to operate in tough conditions due to vibrations and other mechanical stress, they must be able to power various electric and electronic devices and when the main engine must be started, they must be able to provide large currents in order to start large, often multiple gasoline or even diesel engines even when not fully charged. Such requirements significantly reduce the number of potential 1000 CCA marine battery models.
CCA (Cold Cranking Amps), CA (Cranking Amps) or MCA (Marine Cranking Amps) and HCA (Hot Cranking Amps) define the maximum current that a battery is able to provide under certain conditions.
With all the available battery models and brands on the market, finding suitable trolling motor battery often can be daunting task, but it shouldn't be. But before getting new battery or battery pack, one should first write down few things, including size and weight of the boat, motor strength, required trolling time and of course, the funds allocated for the new trolling motor battery.
When describing batteries and their features and characteristics, many abbreviations are used.
Knowing their meanings is very important, because that is the difference between getting the right battery and the wrong battery. And the wrong battery often can cause much more damage than its money worth ...
Deep cycle batteries for recreational vehicles (RVs) have very important purpose - they power onboard electronics and electrical devices while the vehicle's main motor is not working, while being off the grid. RV deep cycle batteries must tolerate deep discharge conditions and cyclic use, but they also must be resistant to vibrations, high and low temperatures, no usage for long time (sometimes for months) etc.
And since these batteries are far from being cheap, it is really important to choose them properly, according to the individual needs and requirements.
